             Summary: Maven possibly not aware of log4j2
                 Key: MNG-5961
                 URL: https://issues.apache.org/jira/browse/MNG-5961
             Project: Maven
          Issue Type: Bug
          Components: Logging
    Affects Versions: 3.3.9
            Reporter: Mike Drob


Using a fresh install of maven 3.3.9 I followed the steps at https://garygregory.wordpress.com/2015/03/23/watch-maven-in-color to add color highlighting to my output. Everything works as expected, however on all usages I would get the warning:

{noformat}
[WARN] The SLF4J binding actually used is not supported by Maven: org.apache.logging.slf4j.Log4jLoggerFactory
[WARN] Maven supported bindings are:
[WARN] (from jar:file:/opt/apache-maven-3.3.9/lib/maven-embedder-3.3.9.jar!/META-INF/maven/slf4j-configuration.properties)
- ch.qos.logback.classic.LoggerContext
- org.slf4j.helpers.Log4jLoggerFactory
- org.slf4j.impl.SimpleLoggerFactory
{noformat}

This looks pretty harmless, and I was able to suppress it by manually adding the line
{code}
org.apache.logging.slf4j.Log4jLoggerFactory org.apache.maven.cli.logging.impl.Log4j2Configuration
{code}
to {{/META-INF/maven/slf4j-configuration.properties}} in {{maven-embedder-3.3.9.jar}}.

I'm not sure that this is a "correct" solution, and I'm not even confident I could explain what effect it has, hence not posting a patch, but somebody with more knowledge might be able to triage this better. Or offer an "official" way to do colorized output.
